The Islamic Revolutionary Guard Corps threatened to expand the Iran war "beyond the region" if U.S. or Israeli attacks against Iran resume, Reuters reported May 20.

The U.S. Senate advanced a resolution by a 50-47 vote to curb U.S. military action in Iran; the House of Representatives is expected to vote on a similar measure, though previous efforts have failed. Separately, Trump met with his national security advisers May 18, hours after he said he had called off attacks on Iran.
